damn. changing the "Ring" value always fixed it for me. I wonder if it s being re-written after you are setting it? the two things are WIF(Windows Insider Fast) and WIS (Windows Insider Slow)
like 10147 is or there was an entreprise version available ??? im on 10147 on slow the registry trick don't work for me
they have change the link address for skip the ESD Generator and also they have change the name's of esd's hahahha
A litle (important) advice... Don't forget to go to Apps & Features, Manage optional features, Add a feature, and install the Insider Hub (its by alphabetical order)
